24VH and Ubiquity 24V ?

[te31]

Hi,

Will plugging an uniquity nanostation (24V) on a 24VH port (I'm thinking of port 2 of WS-6-MINI) work without risk of frying things (switch and/or nanostation)?

Thanks in advance.

I think at the very least, the presence of voltage on the data pairs would remote reset the kit. I wonder if the Ubiquiti Instant AF adapter could be used to convert 48VH to 18V?

DO NOT POWER NON 24VH OR 48VH DEVICES SUCH AS 10/100 LEGACY airMAX GEAR LISTED BELOW WITH PORT 2 OF THE MINI IT WILL DAMAGE THE DEVICE AND THE PORT!

Probably any 1G standard 24V or 48V will be fine since the manufacturer is forced to properly use the center tap of the Ethernet Transformer on 1G devices but with 10/100 they can so a non standard thing with pair 3 and pair 4

I believe Les is powering non VH devices on that port?

I only tested using port 2 with a UAP Pro using 48VH. I don't think the UAP Pro has remote reset capability. <note>I'm pretty sure the smoke would not leak out of anything</note> but I still think the voltage on the data pair could trigger remote reset.

Note: I see reading further down that the smoke can leak out.

Thanks for your answers, I will test and report back ASAP.

I tried a WS-6-MINI:

48VH on port 2 Ubiquity Instant 802.3AF Outdoor 48V POE adapter (18V 0.7A passive output) and when I activated 48VH the netonix switch went off a entered a reboot cycle until I unplugged the instant adapter.

24VH on port 2 with an Ubiquity LocoM5 led to the same off then reboot cycle on the netonix.

24VH on port 2 with an Ubiquity Nanobeam 19 AC (gigabit port) led to reset of the Nanobeam 19 AC and no packet going through, no reboot of the netonix.

No fried switch or antenna but WS-6-MINI port two isn't usable so far, except I assume for AirFiber or powering another WS-6-MINI.

I'm open to ideas, may be there's an adapter somewhere that could work?

Here is a thread on that.

Why would you use a UBNT instant 802.3af adapter in that way?

That is NOT what it was designed for and you can damage it and the switch.

The 802.3.af adapter is meant to plug into an 802.3af ACTIVE POE switch not a PASSIVE POE switch and produce 24V POE out for airMAX radios.

If you want 24V POE simply just log into the switch and set a port to 24V POE.

You can even power standard 10/100 24V (2 pair pins 4,5,7,8) UBNT devices with the 24VH option on port 2 which is 24VH or 48VH only as 24VH works FINE with UBNT 24V devices. Having power on the other 2 pairs will NOT hurt anything as it just get to the Ethernet Transformer on the device on the other pairs and goes nowhere but using that adapter vary well could have damaged the adapter and the switch.

What are you trying to gain by doing such a thing???

Using that adapter with out switches is just WRONG!!!!

UBNT instant 802.3af adapters sole purpose in life:
1) Communicate with ACTIVE POE switch to tell it to turn POE ON on for the port that the adapter plugged into
2) Convert the 48V provided from the ACTIVE POE 802.3af switch (only from pair 3 and 4) to 24V (only on pair 3 and 4)

WHY ON EARTH WOULD YOU WANT TO TRY THAT ON A SWITCH THAT IS ALREADY CAPABLE OF PASSIVE 24V BY SIMPLY TELLING IT TO TURN 24V POE ON FOR ANY PORT THAT YOU WANT 24V PASSIVE POE???????????

That's wrong: port 2 24VH on regular Ubiquity devices doesn't work, please re-read my post I tested LocoM5 (XM, 100M) and Nanobeam 19 AC (XC, 1G) directly plugged on port 2 24VH and didn't get it to work at all.

The only thing I get working on port 2 is another WS-6-MINI (which is nice :).

On port 3-6 Ubiquity 24V work fine as documented.
